Upsampling in Roon 1.3

[David A]

Do you have a link / URL where Roon is saying that? As experienced by others this normally is quite specific to the DAC and it’s settings / architecture.

Here you go:

It gives the reasons for upsampling but if you skip down to the section on reasons not to upsample you'll find the following:

"You paid for some really great hardware that has its own DSP/upsampling


Hardware manufacturers are in a unique position to produce DSP that is tuned to their gear. If you paid for it, use it!"

I've tried upsampling in Roon and never noticed a difference. Since I couldn't notice a difference I've always taken Roon's advice and left it up to the Devialet to handle all upsampling, especially since the maximum sample rate it accepts is 192 kHz and it then upsamples all input to 384 kHz anyway. I prefer to use as few DSP processes so I stream native resolution to my 140 Pro and let Devialet do the upsampling to 384 kHz in a single step rather than let Roon upsample to 176.4 or 192 kHz and then let the Devialet do a separate upsampling to 384 kHz.

I'm 75 and my high frequency hearing isn't what its used to be. If you don't want to take Roon at their word then do the comparison for yourself and see if you hear a difference. If you can't hear a difference then I'd just let the Devialet do all of the upsampling because it's going to be upsampling whatever you feed it anyway.
